-This invention relates to osteopathic tables for use by osteopathic practitioners in treating patients by the movement and stretching of various parts of' the body.

The primary object of the invention is to provide a table of the class set forth embodying mechanical structures which permit a multiplicity of adjustments and movements and also whereby a stretching tension or force 'may be applied 4to a patient and regulated -to accord with existing physiprovide a cal conditions, .particularly in treating the spine and ribs by means adopted 1n osteopathic methods.

A further object of the invention is to table to aid an osteopathic practitionerin treating a patient with increased ease ot manipulation and with more effectiveness in 'correcting irregularities ot the spine and ribs, and especially the cervical and dorsal vertebrae, as well as ordinary curvatures, sprains and the like.

The invention primarily consists in the provision of'a table havingr a section for supporting or holding the torso of the human body and a swinging section which may be lowered by pressure 'and having means for compensating 'for varying weights thereon and operating to return to its original or normal position when pressure is released. i

The invention also consists in the construction, arrangement and combination of elements which will be more fully hereinafter described and claimed in-preferred| form and subject to modification and variations in the proportions and dimensions as well as details of construction withoutdeparting from the scope of the claims.

1n the drawings: Figure 1 is a top plan view of the table embodying the features of the invention.l Fig. 2 is a side elevation of the. same. Fig. is an enlarged View in sectional side elevation of parts of the table sections and particularly illustrating the mechanism coperating with the pillar or pedestal which serves as the support for the Specification of Letters Patent.

whole table. Fig. 4l is a horizontal section taken through the pillar or pedestal near the top portion of the latter. lFig. 5 is a detail perspective v iew of the swivel to which the leg or lower body section is adjust-ably connected. Fig. 6 is a view similar to Fig.

V3 showing av slight modification. F ig. 7 is a horizontal section through the pillar or pedestal shown by F (3. Fig. S is a side elevation of the table showing the pedestal and other parts broken away andillustrating a further modification.

The numeral designates a supporting pedestal or pillar having a hase 6 and a tubular cap 7 movably fitted thereover. rl'he pedestal or pillar 5 has a vertical rack 8 secured thereto and engagedl by a Apinion 9 held between flanges 10 of the cap and fixed on a shaft 11 bearing in said vflanges and operated by. a crank handle or lever 12 secured on one end tliere texteiioily of one of the flanges 10. A locking dog 13 is also operatively disposed between the flanges 10 to engage and lock the pinion 9 against movement. the said dog being thrown into and out of engagement relatively to the pinion 9 by a handle or analogous device 14 exterior ot the flange 10 against which the lever or crank handle 12 is applied and attached to a pin or small shaft 15 to which the dog 13 is fixed. )iy exerting a downward pressure on the lever 12, the pinion 9 is operated and through the rack 8 the cap 7 is moved upwardly, the dog 18 remaining in engagement with the said pinion 9. When it. is desired to lower the cap the dog 13 is released from the pinion' and the capr by its weight, together with the parts supported thereon, .will gravitate or lower. On the cap 7 a frame or bed'lti is secured and `said frame or bed adjustablyv supports or Aholds a main body or torso section 17vr which 5 is hollow. and adiustably connected thereto so as to have a lateral swinging and vertical movementl is an auxiliary or lower body table section 21.whicl1 is so controlled by mechanism more fully hereinafter explained that when it is depressed by exerting a pressure thereon and released from said pressure it will return to its original or normal position, as the case may be, and in acc ordance with its adjustment.

The table sections 17 and 21 may be suitably upholstered and padded, or they may be constructed without upholstery or pads, and each section has means as 22 for applyingfastenings devices or suitable harness or straps for securing the parts of the body on the table'as a whole, and the section 21 is also provided withleg or knee braces or holding means as at 23.

All of the forms of the table shown embody t-he common features thus far described and the same principle of operation so far as depression and automatic return movement of the auxilary or lower body section 21 relatively to the main section 17 are concerned.

Referring now particularly to Figs. 1, 2, 3, 4 and 5, the pedestal 5 at apoint diametricall opposite the position ofthe rack 8 is ormed with an opening 24 in which a swivel member 25 is mounted and as shown in preferred form consists of an upright block-like member or body 26 having openings 27 in theupper and lower ends thereof engaged by swivelbolts 2'8- projecting in-` wardly in opposition from the upper and lower walls of the openin 24. The body 26 vhas la slot 29 extending t erethrougli and an inner pair of lugs 30 on opposite sides 'of the slot. Projecting forward from the body 26 at one side of the slot 29 is a slotted segment 31 which is engaged by a clamping -screw 32 of a hand-operated clamp 33 having an outer cross-head 34 wit-hin easy reaching distance of an operative. vThe screw 32 engages an inner metallic sect-ion 35 of an arm .36, said section 35 extending through the opening 2S) and pivoted in the swivel lmember 25 by means of a suitable bolt or pin 37 extending through openings 38a in the said 'swivel and a corresponding opening in the portion of the section 35 projecting .through the `swivel. The arm 36 continues outwardl under the auxiliary table section 21 and llas its outer extremity reduced and projected upwardly in a plane parallel with a frame 38- supporting the auxiliary table section 21 as at 39, the outer l end of the arm 36, being formed with a guide 40 ofen' adjusting screw 41,' the said guide and its frame 38 may be shifted longitudi-v being in the form of a screw-eye so that by the operation of the screw 4l the section 21 nally. in opposite directions relatively to the section 17 to increase or decrease the distance between the y inner ends` of tthe two table sections. The outer extremity ot' the screw rod 4l is mounted in `a bearing 42 in which 'it freely turns, and on its outer end the said rod has an operating' crank-handle 43. Depending from the frame 38 are guides 44 and 45 which are inthe form of slides movable on different portions of the arm 36 to maintain the frame 38 and auxiliary table section 2l in constant relation as' to position to the said arm 36. The inner end of the arm 36 or rather the section 35 of said'arm 'extends into the upper portion of the pedestal 5, and secured thereto is the upper extremity of a retractile spring 4 6 having 'its lower extremity connected to a tension regulating mea-ns 47 embodying an eye-bolt 48 `to which the end of the spring is attac-hed, a

foot plate 49 engaged by the said eye-bolt, an angle arm 50 having its lower end attached to the plate 49 and its upper end movably connected to a link 5l projecting through an opening 52 inthe pedestal 5,-and an operating lever or adjusting device 53 secured to one end of a shaft 54 having bearing in ears'55 and to which the link 51 is fixed'. The link 51 operates as a crank-arm-and with the shaft 54 constitutes crank mechanism for adjusting the arm 50 and. the plate 49 and boltg48. The-lever-53 is maintained in itsadjusted positionthrough the medium of suitable 'cranking devices comprising a slotted segment 56 secured to the cap 7 and under whlch the said lever 53 projects, and engaging the lever and the segment 56 is a suitable clam ing screw 57 which is freely -shiftable in t e slot of said segment wheir loosened. The purpose of mdiying the tension of the spring 46 is to compensate for the weight pressure on the auxiliary table section 21 and also to always maintain the said :iiixiliary section. so far as the action of the spring is concerned, in horizontal position. The adjustment of the arm 36 and the movement therewith of the. auxiliary section 21 in a downward direction will be performed against the resistance of the i spr1ng46, and to maintain the said auxili iary section 21 in depressed positlon the clampingdevice 33 is brought into play and 1s operated so as to tight-ly engage the slottedv segment. 31 .and thereby hold. the

section 2l at any angle of depression that may be desired. `When the clamping device 33 is released the spring 46 by its retraetile e'or'l'and through the arm 36 and stictirm -35 of the latter will automatically elevate the auxiliaryysection 21 and its frame 38 to normal position or to the' position it may have originally had prior to depression thereof.

It will be understood that the auxiliary section 21 may be elevated above a horizontal plane and such position, maintained by the same means as just explained. The auxiliary section 21 through the medium of inseam the position of the said auxiliary section 21 maybe relatively to a horizontal plane. v vIn the form of the table illustrated by Gand 7, the essential features heretofore described are embodied and similar parts have like reference characters applied 4 thereto, `and the specific differences will now .be described. The arm 36 in the modied Y form shown by Figs. 6 and 7 is provided Y with a metallic section which is pivoted 1 in Vthe slot 29 of the swivelmember 25 and the adjustment of ,the` said arm is accomplished through the medium of the slotted segment 31 and clamping device 33 to raise and lower said arm and the auxiliary table i section 21, below or above a horizontal plane in a manner Isimilar to the construction hereinbefore described. The longitudinal t adjustment of the auxiliary section 21 is also present in Vthe modification shown by I *Figsr `6and 7 and the samemeans\will be used for th'm particular movement as illustrated by 2; In the modification, however the spring 46, heretofore described, is

replaced by a Weight 58 which is vertically i movable in thepedestal 5 and has'a link 59 l l secured to the' upper end thereof and to the inner end f a shifting bar 60 associated with the section 35 of the arm 36 and longi.

,tudinal'ly slotted as at'l to move relatively to the pivot bolt-or pin 37 .Whichextends fthrough the said slot.' To maintain the section 35 and arm 36, a lug 62 is formed shifting bar 60 in proper relation to the with or secured to the section 35 and also .i .projects througlri,y the slot 61 of the said "shifting bar.

/ The shifting bar is formed with rack teeth 63 in a portion of its lower edge, said teeth being held in continual mesh with a'pinion 64 rotatably's'upported on a depending portion of` the section 35 and havlng anloperating crank-handle 65, as clearly *shown by Fig. 6. The purposel of the shifting bar 60 'and the adjustingmeans therefor vis to modify the leverage of the arm 36 to compensate for` varying Weight pressures that may be imposed on the auxiliary section '21 and when the saidrauxiliary section is 7depressed it may be maintained at any an- 'gle desired relatively to a horizontal plane through the clamping means coperating with the arm 36, but as soon .as the said clamping means is released the weight 581 1 will be free .to act and automatically raise or elevate .the auxiliary section 21to itS.`

original or normal position. In view of the fact that the linkl 59 is loosely attached at its opposite extremity to the weight and shifting bar, the auxiliary section 21 and the parts coperating therewith may be readily shifted laterally in opposite directions in 65; the same' manner as 1n the construction hereinbefore explained.

In the form of the device. shown by Fig. 8 the essential features of the invention are also embodied in a manner similarto the constructions heretofore described vand like reference characters are applied to the common features. In the vform of the table shown :by F ig. 8 the auxiliary table section 21 is not longitudinally adjustable and has its inner end hinged as at 66 to an upper extension 67 of the swivel member 25. The arm 36 is sl orter than in the preceding structures butl is adjustable in the swivel member 25 vertically with respect to a horizontal plane and hasthe spring a6 attached tothe inner end thereofin a manner similar tol the construction of the table disclosed by Figs. 1, 2, 3 and 4. Depending from the frame 3810i' the auxiliary section 21 is a screw-rod 68which is pivotcd at its upper end to said frame 38 .and has lits screwthreaded portion E, adj ustably projecting through the outer end of the arm '36. Disposed on the upper'edge ofthe 211711186 and always maintainedin the same relative relationthereto is a screw ac ljusting.V device) having an operating hand-wheel 70 and by operating the latter. wheelthe auxiliary table section2l may beelevated or depressed relatively tothe arm 36 without adjusting the latter and after the spring 46 has-'been setto exert a specific tension or. spring action on the auxiliary table section 21. The

downwardf adjustment of the screw-rod 68 and the table section 21 will,however,tighten the spring46, or thetensionofpthe spring is increased and a reverse operation of the screw-rod lessens the tension on the spring, and by this means variations in pressure on the section 21 may be readily accomplished andv accommodated.

In'the use of any one of the forms of table shown in the accompanying drawings the patient is placed on the sections 17 and 21 and the different parts of the body` secured.

By usting the auxiliary section 21 or by moving it laterally in opposite directions as well as vertically various movement treatments may be pursued, and, furthermore, the body Amay bc stretched to rectify spinal and vertebral irregularities, and when the clamping means for the arm 36 is loosened the section 21. may be 'readily depressed against' the resistance of the spring or the Weight in the-pedestal 5 and when the pressure is'releasedfrom said section the latter will be caused to return to its original position, with great convenience in treating deformitiesand in expeditiously manipulating the tablev without requiring a delay, or the inconvenience incident to releasing and securing devices that are ordinarily adopted for holding Aparts of tables of this class in elevated position against the Weight pressure imposed thereon.

The table as a whole through the mechaand means operating with the auxiliary section to restore the latter to its original position from either a depressed or lateral position.
